I have my 4 years old DELL Latitude 7000 series laptop with this type of configuration. The difference is I have 128GB M.2 SSD and 500GB HDD. I work with few major CAD and 3D software including AutoCAD 2015, 3ds Max 2015, Revit 2017, Solidworks 2013, Sketchup 2017, Adobe CS6 (PS, AI, ID, AE, DW, FL), MS Office 2016. These program installed on a 128GB SSD with Win10 is good to go.
Working files, videos, downloads, rendering destination folder will all be directed to folders in HDD.
P/S: I installed library (& Materials) files for Revit 2017, Solidworks 2013 on Hard Drive to save some hot storage space.
IMO, if you don't plan to spend a buck on upgrading this machine in next 3 years, 250GB SSD + 1TB 5400RPM HDD is a good choice.
Please let me know what you think.
